It is inconceivable that Galileo was the first person to observe a discrepancy with Aristotle's predictions. Aristotle's observations had been incomplete, his interpretation a vast oversimplification. Galileo, who had a flair for the theatrical, did the experiment by dropping a bullet and a heavy cannonball from a tall tower. It looks like they hit the ground at exactly the same moment. Now repeat the experiment, but make it into a race between the coin and your shoe. Europeans believed him for two thousand years. That's why Aristotle wrote that heavy objects fell more rapidly. The paper takes much longer to hit the ground. Stand up now and simultaneously drop a coin and a bit of paper side by side. But there is something impressively consistent, universal, and inexorable about the way things fall. If one stretch of a river flows more rapidly than another, it may be only because the channel is narrower there, which is just an accident of the local geography. A walking person who speeds up is making a conscious choice. Other examples seem less likely to have deep significance. The early pioneers of physics had a correct intuition that the way things drop was a message directly from Nature herself about how the universe worked. The motion of falling objects is the simplest and most common example of motion with changing velocity. To understand the concept and properties of acceleration.data collecti When you are ready to collect data, click Collect to as you have practiced. Use two hands and pull your hands away from the ball after it starts moving so the ore no picked up by the Motion Detector.After the toss, catch the ball at a height of 0.5 m above the detector and hold it still until data collection is complete.A toss so the ball moves about 0.5 m above the detector works well.Hold the ball approximately 0.5 m directly above the Motion Detector when you start data collection.To achieve the best results, keep in mind the following tips: It may require some practice to collect elean data. During data collection you will toss the ball straight upward above the Motion Detector and let it fall back toward the Motion Detector. Open the file "06 Ball Toss" from the Physics with Vernier folder. Place the Motion Detector on the floor and protect it by placing a wire basket over it.
Set the Motion Detector sensitivity switch to Ball/Walk. Connect the Vernier Motion Detector to a digital (DIG) port of the interface.
